A block is given a short push and then it slides with constant friction across a horizontal floor. Which statement best explains the direction of the force that friction applies on the moving block?
A 3.00 kg block slides down a ramp which is at an incline of . The friction force between the block and the ramp is 5.20 N.
What is the coefficient of kinetic friction between the block and the ramp?
At what incline will the box slide at a constant velocity?
A skier skies downward along a slope inclined at below the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.100.
Calculate the acceleration of the skier heading down the hill.
Find the angle of the slope down which this skier could coast at a constant velocity. Ignore air resistance.
